Detailed Description

A table column.

A WTableColumn is returned by WTable::columnAt() and managing various properties of a single column in a table (it is however not a widget).

You cannot access table cells through the column. Instead, to access table cells, see WTable::elementAt().

A table column corresponds to the HTML <col> tag.

WTable, WTableRow

Member Function Documentation

int Wt::WTableColumn::columnNum

(

)

const

Returns the column number of this column in the table.

See also:

WTable::rowAt()

const std::string Wt::WTableColumn::id

(

)

const [virtual]

Returns the (unique) identifier for this object.

For a WWidget, this corresponds to the id of the DOM element that represents the widget. This is not entirely unique, since a composite widget shares the same id as its implementation.

By default, the id is auto-generated, unless a custom id is set for a widget using WWidget::setId(). The auto-generated id is created by concatenating objectName() with a unique number.

WWidget::jsRef()

Reimplemented from Wt::WObject.

void Wt::WTableColumn::setId

(

id

)

Sets the CSS Id.

Sets a custom Id. Note that the Id must be unique across the whole widget tree, can only be set right after construction and cannot be changed.
